Los Angeles -- Carole King is the latest artist to join the exclusive 10 million club, though it took her "Tapestry" album 24 years to get her there.
Ms. King was certified last week by the Recording Industry Association of America for domestic sales of 10 million copies of the seminal 1970s album, which spent 302 weeks on Billboard's pop chart, compared with record-holder Pink Floyd's "Dark Side of the Moon" with 741 weeks and third-place "Led Zeppelin IV" with 259 weeks.
Ms. King joins only 21 other artists and 26 albums that have hit the stratosphere of the 10 million club. She also becomes the only female member besides Whitney Houston.
Michael Jackson still holds the title with 24 million copies of "Thriller" sold, but the Eagles, who have two titles in the club, are close. Their greatest hits LP is at 22 million and climbing.
Other artists with two albums in the club are Bruce Springsteen, Ms. Houston, Pink Floyd and Garth Brooks.
At 24 years, Ms. King's bona fide classic took the longest to reach 10 million. In comparison, Hammer's "Please Hammer Don't Hurt 'Em" took only one year to sell 10 million in 1990.
To fully understand Hammer's feat, one must look at the best-selling albums in rock history and see that it takes an average of 12 years to reach 10 million.
Elton John, Pink Floyd and Led Zeppelin waited more than 20 years for their "diamond" albums -- the term many call the 10-million-plus sellers.
